Halfway Between 5 and 310

When you ask "What number is halfway between 5 and 310?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=310.

Halfway Between Line

To find the number halfway between 5 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 310 into our formula, we get:

(5 + 310)/2 = 157.5

Thus, the number halfway between 5 and 310 is 157.5.

To check that our answer is correct, we subtract 5 from 157.5 and subtract 157.5 from 310 and compare the two numbers:

157.5 - 5 = 152.5
310 - 157.5 = 152.5

As you can see, the halfway number is 152.5 higher than 5 and 152.5 lower than 310. Therefore, our halfway between answer of 157.5 above is correct.
